Detailed Description
Delphi TC2903 is engineered for the front right lower suspension position on 2001-2005 Lexus IS300 applications. The part uses a steel body, chloroprene rubber dust boot, and a tapered stud design to support secure fitment at the steering knuckle connection. Delphi applies OE-level dimensional and material checks to help maintain proper compatibility between the replacement part and the original suspension layout. This part cross-references MOOG Chassis Products K500067 for the same application.
Common Issues This Part Addresses
- Front suspension looseness or play at the lower ball joint
- Clunking or knocking from the front right suspension
- Uneven tire wear related to worn suspension joints
- Steering wander or reduced front-end stability
- Visible dust boot damage or joint contamination
Installation Notes and Tips
Verify the front right lower position before installation and confirm stud taper, mounting-hole spacing, and thread specifications against the original part. Because this is a bolt-on assembly, clean the mounting surface and inspect adjacent suspension components for wear before reassembly. After installation, a professional wheel alignment is recommended to restore correct suspension geometry on the Lexus IS300.
Quality Assurance
Delphi tests steering and suspension components across extreme temperature and corrosion conditions, including sub-zero cold, high heat, and extended salt-spray exposure. That validation process supports OE-style durability for Lexus IS300 front suspension service.
